Why? Really, why have them? They're 20th-century relics, usurped by Bluetooth and WiFi and 3G. This thing isn't a workstation, and it isn't for archiving. It's not supposed to replace your desktop with its poundage of boxes, cables, gizmos, most of which is rarely used; if you need them, there they are. This thing is supposed to be super-ultra-light, with nothing you don't need most of the time.
Welcome to the wireless 21st Century. Keyboard? wireless. Mouse? moot. Storage? cloud. Content? streaming. Printing? remote. An occasional tethering aside for deep updates, recharging, and collecting what I really want on-hand (ex.: 100 favorite CDs, not all 1000; 10 favorite movies, not all 200 uncompressed), and ... who needs physical ports?
Sorry; no sale. If this thing is to be a glorified toy, then you may be right. If they want to position it as a true tablet compute platform, gotta have those “relics”, friend. Look at competing products; tell me that they are all wrong.
